IRRIGATION HEAD-GATE.

Application filed June 19, 1905, Serial No. 265,928. Renewed May 20.1907.

To all whom it may concern:

Be it known that 1, JAMES M. TAYLOR, a citizen of the United States,residing at Whittier, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Irrigation Head-Gate, ofwhich the following is a specification.

One object of this invention is to provide a cheap and simple head-gatewhich can be used in the stand-pipes of irrigating systems to bank upthe water to cause it to flow through the outlets in the dees or otherupright pipes leading up from the main irrigating pipe.

In southern California, some irrigating systems consist in an inclinedmain pipe or pipes of concrete, clay, or other material buriedsufficiently in the ground to be out of the way of cultivation, andprovided at requisite intervals with upright pipes which are in someinstances cylindrical and in other instances D-shape, or of some otherdesired form, and are provided with outlets above the buried pipethrough which the water is made to flow by temporarily closing the mainpipe for that purpose The invention is also applicable to be used with astuffing box for the stem which operates the gate, thus dispensing withthe necessity of locating stand-pipes along the irrigating main. In thefollowing specification reference will be more particularly made to thestand-pipe construction, but it is to be understood that the inventionmay be applied with a stuffing box aroundthe stem of the handle whichoperates the gate.

The following drawings illustrate the invention, and referring thereto:Figure 1 is a fragmental view of an irrigating system in which myinvention is applied. Fig. 2 is an enlarged plan section of thestand-pipe in which my newlyinvented head-gate is applied. Fig. 3 is anelevation of the head-gate viewed from the inside of the stand-pipe, asection of a fragment of which is shown; line ow Fig. 2, indicates thepoint of view looking in the direction of the arrow. Fig. 4 is a likeview with the gate raised. Fig. 5 is an enlarged section on line x xFig. 3.

1 is a head provided with a main opening 2 and a projection 3 on oneface around the opening.

4 designates ways on opposite sides of the opening 2, and 5 a flexiblesheet in the Ways engaging the top of bead or projection 3 and movablethere-across to open and close the opening. Sheet 5 may be provided witha handle 6 for operating the same The head 1 is preferably formed of asheet or galvanized iron lapped over in laps 7, 8, at the two edges onone face of the sheet to form guiding means comprising the ways 4 forthe gate 5 composed of the flexible sheet above referred to, which isalso preferably of galvanized llOIl.

Specification of Letters Patent.

Patented Aug. 20, 1907. $erial No. 374,755.

The projection 3 of the head is formed by a bead stamped in the sheetmetal and projecting from the plane of the overlapped face, so that whenthe edges of the flexible sheet are in the ways formed by the lappededges said sheet is held with a tension against the face of the head.

9 indicates a lap formed at the bottom of the head by bending the sheetin the same manner as it is bent to form the ways 4. This affords achannel or seat 10 into which the bottom of the gate may enter when thegate is fully closed down.

11 designates the main pipe of the irrigating system in which the waterflows in the direction indicated by the long arrows in Figs. 1 and 2.

l2 designates the stand-pipe in which the gate i mounted, the same beingfastened against one end I) of the main pipe. The sections a and b ofsaid main terminate in the stand-pipe 12 in the ordinary way, and thehead 1 is placed against the open end of the outlet section b of themain and fastened in place by cement 13 in the stand-pipe. The laps 7, 8and 9 are of considerable width so as to hold the gate firmly and trulyin place, and also to allow the head to be firmly fixed in the concreteor cement 13 without interfering with the resiliency of the laps.

It is to be understood that I do not limit the invention to the specificdetailed construction shown, but may vary from the same withoutdeparting from the principle of the invention.

The head being placed on the outlet section b of the main 11, receivesthe pressure of the water in the section a of the main and in thestand-pipe 12, and when the flexible gate formed of the sheet 5 isclosed, the pressure ofthe water forces the same firmly against the beadand closes the head-gate practically water tight.

In practical operation the head-gate can be raised to partially or fullyopen the opening 2 to give the required head in the upper section a ofthe main.

What I claim is:

1. A head-gate comprising a head formed of a sheet having a main openingtherethrough and around such opening a bead projecting from the plane ofthe sheet, a flexible closure engaging the top of the bead to form aclosure for the main opening, and guiding means for said closure.

2. A head-gate comprising a head formed of a sheet lapped at two edgeson one face to form ways, and having a main opening and around suchopening a bead projecting from the plane of the overlapped face, and aflexible sheet in the ways and engaging the head to form a closure forthe main opening.

3. A main provided with a stand-pipe, said main having sections openinginto and from said stand-pipe, a head comprising a sheet furnished witha bead extending around the opening leading from the stand-pipe, and aclosure movable longitudinally of the stand-pipe across an openingbetween said ways and around such opening a the top of said Dead to openand close said opening leadbead; and a flexible sheet engaging in theways adapted ing from the stand-pipe. to seat in said seat and to engagethe bead to form a 4. A main, a stand-pipe for the main, a sheet metalclosure for the opening. 5 head having a main opening, a bead around theopening In testimony whereof, I have hereunto set my hand at 15 andedges lapped to form ways, a concrete, cement or clay Los Angeles,California, this 10th day of June, 1905. body constructed to hold thelapped edges, and a sheet in JAMES M.
